To all whom it may concern:

Be it known that I, Gnonon B. (ilFFURl), Jr., a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey. have invented a new and Improved Heat-Absorbing System for Internal-Combustion Engines, of which the following is a full, clear, and eX- act description.

This invention relates to what may be termed heat absorbing systems for internal combustion engines, and-has for an object the provision of an improved construction whereby the heat absorbed from the engine is communicated to air" supplied to the carbureter.

Another object of the invention is to provide a heat absorbing or cooling system whereby radiators for internal combustion engines for automobiles and for other purposes are eliminated.

A further object of the invention is to rovidc a more uniform and even condition 111 respect to the heat of the cylinders and the incoming fuel.

In the accompanying drawing Figure 1 is a side view of an engine with an embodiment of the invention applied ihereto, certain parts being broken away for better illustrating the construction.

Fig. 2 is a transverse sectional view through Fig. 1 on line 2-2.

Fig. 3 is a top plan View of one end of the heat absorbing member shown in Fig. 1, part being broken away.

Fig. 4 is a fragmentary sectional. v ew through the auxiliary inlet of the carburelter' shown in Fig. 1, the same being on an en larged scale. 1

Referring to the accompanying drawing by numerals. 1 indicates an engine of any desired kind which may be used at any place, as for instance, on an automobile, and when so used the engine is arranged so that the pipe 4 ill be at the front so that the, travel in the direction of the arrow tlll lllily I 3 and pass through the opening in plpe t into the heat absorbing member a. Member- 5 comprises a shell (3 of metal or any suitable material connected with the headers 7 and 8, said headers being hollow and connected by tubes. 9 whereby air entering the opening in pipe 4 will fill header 8 and pass through the tubes 9 to header '7 and fg'ora thence out the discharge opening 10 into E; pipe 11. The air passing through pipe 11 will be discharged into the carbureter 1.2 through the primary inlet. 13 and also through'the auxiliary air inlet l-l.

The engine 1 is provided with water jackets 15 and 16 for the respective cylind said water jackets being connected with t p pipes 17 and 18, said pipes extendi through the header 8 but connected there with so as to make a water-tight fit, where by the water from the water jackets re freely pass into the space above header and circulate around between the tubes Preferably, when the water jackets 15 a 16 are supplied with water through the i let pipe 19 sufficient water is used to the water jackets and also to substantial fill the space between headers 7 and 8.

By this construction and arrangement, as the water is heated by the respective cylin ders said water will rise and the cooler w ter in the space or chamber 20 between t headers 7 and 8 will move downwardly. This upward and downward movement 0" the water continues as long as the engine i in use because of the tact that the air pass-- ing through tubes 9 into the headers continually produces a cooling efiect by chest ing the heat units from the water. will not only cool the water so that the ter mayact properlyiqon the cylinders be the heat units thus reheoved from the wa" are utilized for heating the air and the heaw ed air is utilized by the carbureter 12, so that a fuel fed into the cylindens will be a a temperature more nearly equal the te pcrature of the cylinder, thus giving bet ter and more uniforni comhustion and more uniform action of the engine. 1 tubes 5) may be threaded into place screwed into place in any suitable man. as well as the remaining parts may be uected together in any suitable manner long as the structure will provide for a c culation of water as described and also circulation of air. The pipes 17 and shown as connected to the top of the on but these pipes could be connected to side or at any suitable point without i parting from the spirit of the inventi The tubes 9 are connected to.-the top anc bottom piates of the headers so that the air and Water will be entirely separate. These tubes may be held in place in any suitable manner Without departing from the spirit of the invention.

What I claim is: V

1.. In a heat absorbing device for internal combustion engines, the combination With an engine having a Water jacket, of a casing connected With said Water jacket so that the Water in the Water jacket and the Water in the casing may freely-circulate, said casing being provided With a pl rality of air pipes and a headerat each'endio said air pipes,

l5 mcans'forming an air inlet for one of said headers, and a pipe connected to the other header through which the heated air is discharged, said last mentioned pipe extending to the carbureter of said engine supplying neenvsa heated air to main and auxiliary air inlets thereof.

2. In a device of the character described,

the combination With an internal combnsthe engine for absorbing heat units, said means including a space for the circulation of Water, an air compartment above and-below said Water space and pipes connecting said compartments, means for connecting the space for circulating the Water With the Water jacket, and means for connecting the upper air compartment with said carbureter whereby the temperature of the Water is reduced and the temperature of the air supplied to the carbureter raised.
